balaur

Possibly from a pre-Roman (Balkans)substrate word, maybe Dacian *balauras, *beleuras, akin to Albanian boljë, bollë, bullar. May also have a relation to Serbian blavor, but it is uncertain which language borrowed from which. Another theory suggests Latin belluarius, ultimately from bēlua; however the normal result in Romanian would have been *bălar. Influence from laur may have affected it, but it is uncertain why this analogy would be made.
